Particles do not appear on server

[DrFrev]

As the title says, particles appear to the client holding the swep but no one else.

function SWEP:Think()
	if (SERVER) then return end;
	if (self:GetNetworkedBool("IsAlive")) then
		if (!self.hasHooked) then
			self.hasHooked = true
			hook.Add("CalcView", "MyCalcView", MyCalcView)
		end
		self.SmokeTimer = self.SmokeTimer or 0
        if ( self.SmokeTimer > CurTime() ) then return end
        self.SmokeTimer = CurTime() + 0.03
		
		local vOffset = self.Owner:LocalToWorld( vector_origin ) + Vector( math.Rand( -3, 3 ), math.Rand( -3, 3 ), math.Rand( -3, 3 ) )
		local vNormal = (vOffset - self.Owner:EyePos()):GetNormalized()
		local particle = self.emitter:Add("particles/smokey", vOffset)
			particle:SetVelocity( vNormal * math.Rand( 20, 50 ) )
			particle:SetDieTime( 4.0 )
			particle:SetStartAlpha( 255 ) 
			particle:SetStartSize( math.Rand( 100, 130 ) ) -- 20, 36
			particle:SetEndSize( math.Rand( 18, 36 ) ) --24, 48
			particle:SetRoll( math.Rand( -0.5, 0.5 ) )
			particle:SetColor( 50, 50, 50 )
	else 
		if (self.hasHooked) then
			self.hasHooked = false
			hook.Remove("CalcView", "MyCalcView")
		end
	end
end 

Any help is appreciated.
